Tattoo?

So the thing is, I'm thinking of getting a tattoo. Maybe. I don't know. Is there anything you think I should know before I decide? and if I decide to do it, what should I look for in a place? It kind of scares me, but my sister has one and she had a successful experience, so... Does it hurt? I sound like a wimp, I know. I did give birth 3 times, I suppose I should be able to handle getting a tattoo right? If you have one, how long have you had it, where is it, what is it and do you still love it? oh, and how did you decide what design to go with? Ok, that's it for now, thanks for any info you have for me!!
